Geochemistry of tertiary tholeiites and picrites from Qeqertarssuaq (Disko Island) and Nuussuaq, West Greenland with implications for the mineral potential of comagmatic intrusions

, 1997
Tertiary continental flood basalts on Qeqertarssuaq and Nuussuaq in West Greenland contain similar to 3 km of picrites and variably contaminated tholeiites.

Olivine-hosted melt inclusions in Hawaiian picrites: equilibration, melting, and plume source characteristics

, 2002
Olivine-hosted melt inclusions in tholeiitic picrites from five Hawaiian volcanoes (Koolau, Mauna Loa, Kilauea, Loihi, and Hualalai) have major and trace element compositions that illustrate the magmatic characteristics of ocean island volcanoes and the ...

Petrogenesis of the Deccan high-Mg basalts and picrites

Contributions to Mineralogy and Petrology
AbstractTholeiitic basalts and picrites from the Deccan Traps were used to constrain the pressure and temperature conditions of mantle melting for their origin. Clinopyroxene thermobarometry indicates that all Deccan tholeiites crystallized at low pressures in the upper crust (< 6 kbar/1047–1221 °C).
